Title: Detecting and locating sheath short circuit to earth for cable or pipeline - applying inductive measuring process during operation of system earthed at both ends
IPC: G01R31/08
Filed: 1991-01-03
Abstract: A certain capacitative current (IC) escapes to earth through the capacitance of the sheath insulation. An insulation fault adds a fault current (IF) to this capacitative current according to the resistance of the fault. Since this is essentially ohmic in nature it differs in phase from the capacitative current arising through the insulation of the system. The currents (11, 12) and voltages (U1, U2) producd by induction transformers can be measured at both ends both as regards amt. and phase. Alternatively, these variables can be measured at one end only while the current (I2) for the measuring signal is regulated to approach zero through a regulating circuit. The current changes in amt. and/or phase if an insulation fault to earth arises. This can be displayed or transferred to a measurement value registering station. USE/ADVANTAGE - Telecommunications or power cable. Pipeline with insulating sheath. Reduces interference outside the measuring section.

Patent DE-4118074-A1 (DE)
Inventor: OBRIST BASIL
IPC: B23Q3/157
Filed: 1991-06-03
Abstract: The magazine, having a fixed place in a manufacturing plant, is intended to cooperate with at least one machining device and with a handling device associated with said machining device in order to automatically exchange tools and/or workpieces on said machining device. The magazine comprises a rotating rack having a plurality of storing planes mounted upon another on a support for bearing the objects to be handled. Said rotating rack is designed as a separate constructional unit which is exchangeably inserted in a stationary part of the magazine, which stationary part comprises means for rotating said rotating rack. In this manner, the space needed by the auxiliary devices in the magazine station as well as the moving space of the handling device is considerably reduced, due to the fact that even in a prolonged operation of the manufacturing plant one sole magazine is sufficient, and that thus, for the exchange of the objects to be handled, the action of any grip means is limited to this sole magazine.

Inventor: DUESSELBERG HARTWIG
IPC: F24D1/00
Filed: 1992-07-21
Abstract: In the method for heating domestic water, temperature layering with a hotter and colder region is produced in the domestic water. The hot water is used to heat or preheat the domestic water situated in the colder region, and to heat the domestic water situated in the warmer region condensing steam is used. In this arrangement, the hot water is used in a priority circuit for heating the domestic water. As hot water, use may be made of residual heat-carrying condensate, for example distant steam-pipe drainage condensate which is available in any case. In addition, the condensate produced by the condensing steam is used to heat the domestic water. The water heater (1) has a domestic-water tank (2) with a steam-heating assembly (16) and a hot-water heating assembly (26) through which condensate flows. The steam-heating assembly (16) is arranged in a hotter region and the hot-water heating assembly (26) in a colder region of the domestic-water tank (2), thereby reducing the temperature difference between the steam-heating assembly (16) and the domestic water. <IMAGE>
